Years ago when Kaley raced kid kart. There were nights when I thought other racers who were beating us were not legal or something was goin on. Well the problem was we hadn't paid our dues yet (not enough seat time). So my message is seat time is the key to success, you have to put forth the effort, and your driver has to do their job too. Until your driver can go around NTK at full speed (not lift) except turn three and a slight lift for turn seven you have not reached the karts potential. Here's a couple of tuning tips that helped us back then- 87 octane pump gas,8 ounces per gallon of castor oil, use an NGK BPMR7A spark plug and a tach is a must your motor should turn 10,800-11,300 (STOCK)

Thanks for the tuning tips Mike. That is very good information.I would add that a 58 jet works 99 percent of the time for us while using the K&N 1250 air filter. Keep it cleaned and slightly oiled. Also cleaning the carb regulary before or after each race weekend will only take 5-10 minutes but will help to keep the kart running at its best.I also clean the filter in the tank at this time and often check the gas cap for proper ventilation.

Finally, avoid running the Ethanol enriched pump fuels if at all possible. I find that it makes the motors run inconsistantly leaner, it is hard on aluminum, and it attracts water. You can search for stations that sell gas without the Ethanol at www.pure-gas.com

And you can drive for hours to find one of these stations when you are out of state huh Jeff? What we do for these kids. Also a new set of tires work really well after they have figured out the most basic of driving skills. It's hard to put a time stamp on old tires, but you can run one set of new tires the whole year if you take care of them. The thing is with the old ones you never know how old they are and they lose their grip eventually. Generally it is better for a kart to be too hooked up than too loose. When the driver gets faster then you start making other changes to free it up. A kid that is constantly having to save it just to get around the track with any speed will take more time to get confident.
